Parameter influence on downward flow. The results from the 2d-FFT velocity estimation of a wide range of welds are shown in Fig. The most dominant velocity* is presented in the graphs, but it is interesting to note that the maximum downwards velocity in the streak images was estimated to be as high as 25m/s for 15kW laser power.
